Operations and Maintenance <br />Monitoring <br />The solar garden site will operate and be monitored 24 hours a day, 365 days a <br />year after construction has been completed. <br />Equipment Inspection <br />Equipment inspection will occur at regular intervals, including: <br />■ PV modules: visual check of the PV modules, tracking system and surrounding grounds to <br />verify the integrity of the PV modules and racking structure, or the presence of animals <br />and nests, etc.; <br />■ Inverters, transformer and electrical panels: visual check of the devices including the <br />connection equipment and the grounding network. <br />■ Check for presence of water and dust; <br />■ Electrical check: measurement of the insulation level and dispersion. <br />■ Check of the main switches and safety devices (fuses); <br />■ Noise: check of abnormal sounds; <br />■ Cabling and wiring: visual check of electrical lines (where visible) and connection box to <br />verify its status. <br />Performance Monitoring <br />Performance monitoring will consist of a real-time and continuous assimilation of the data <br />acquired by the facility meteorological station, energy meter and SCADA system. Operators <br />and or maintenance personnel will be immediately notified of abnormalities so timely <br />corrective action such as repair or replacement on: modules, racking, the collection system, <br />and etc., can occur. <br />Facility Maintenance <br />Routine maintenance of the Project will include road maintenance, fence and gate inspection, <br />and lighting system checks. Module washing is not needed on a scheduled basis. Rain keeps <br />the modules sufficiently clean and the site is vegetated to keep dust down so that washing <br />modules would occur infrequently and only as determined by maintenance technicians. Snow <br />and ice removal is not needed. The system is designed to shed rain, snow and ice. Vegetation <br />maintenance will include scheduled mowing and spot spraying weeds using registered <br />herbicides. <br />Maintenance Frequency <br />The electrical and mechanical components of the community solar garden would be checked <br />on a regular basis to ensure safety and reliability. The maintenance schedule would range from <br />weekly to yearly depending on the component. <br />315 Manitoba Avenue, Suite 200, Wayzata, MN 55391 <br />
